HYDROCARBON-BURINER.

Specification of Letters Patent.

Application filed. May 1, 1913. Serial No. 764,852.

To all whom it may concern Be it known that I, W'AL'rnn S. MUM- MERY, acitizen of the United States, residing at Minot, in the county of l/Vardand State of North Dakota, have invented certain new and usefulImprovements in Hydrocarbon-Burners, of which the following is aspecification, reference being had therein to the accompanying drawing.

This invention relates to hydro-carbon burners and has for its objectthe production of a simple and eflicient burner wherein an eiiicientcombustion may be produced so as to cause a uniform heat to be createdby the flames from the burner.

Another object of this invention is the production of a simple andetiicient means for feeding the water to the boiler and keeping thewater at a uniform height.

With these and other objects in View, this invention consists of certainnovel construetions, combinations and arrangements of parts, as will behereinafter fully described and claimed.

This invention is illustrated in the accompanying drawings, whereinFigure 1 is a fragmentary side elevation of the burner showing the watersupply tank in section. Fig. 2 is a top plan view with one of theba'ille plates partly broken away of the burner and the secondary battleplate removed. Fig. 3 is a section taken on line 3-3 of Fig. 1. Fig. iis a section taken on line 1--4 of Fig. 3. Fig. 5 is a detailperspective of the supporting member for the water supply tank. Fig. 6is a detail perspective of the heat pipes through which the Water isadapted to pass. Fig. 7 is a perspective view of the boiler used inconnection with the present device. Fig. 8 is a detail transversesectional view showing the relative arrangement of the steam supply andburner. Fig. 9 is a perspective view of the discharge nozzle used inconnection with the present invention.

By referring to the drawings, it will be seen that 1 designates the trayor pan which is provided with a flange 2 extending entirely around thesame. This tray or pan 1 is provided with apertures3 formed in the sidesthereof for facilitating the passage of air into the tray or pan andcause an cilicient draft therethrough. An asbestos plate 4: is placed inthe bottom of the tray or pan 1 and is adapted to be saturated with oilwhen the burner is first lighted so as to efliciently heat the boiler 5prior to the generation of the steam. It, of course, should beunderstood that the steam will soon be created within the boiler afterthe oil in the bottom of the pan has been lighted and the flame willburn from the burner pipe in the manner to be hereinafter described.

The boiler 5 is preferably formed of a rec tangular body being set uponone of the flanges 2 as illustrated in Fig. 3. This boiler 5 is providedwith an inlet pipe 8 which pipe is connected to the Water supply tray 9.The boiler 5 is also provided with a discharge outlet 10 which dischargeoutlet is provided at one end with an overhanging flange 11 adapted tobe engaged by the closure cap 12. A pivoted link member 13 is secured tothe top of the tank 5 and is adapted to engage the upper face of the cap12 to hold the same firmly over the outlet aperture 10. The cap 12 isprovided with a discharge pipe 14 to which is connected the stub pipe 15for conveying the steam from the boiler into the several pipes of theburner.

The pipe 15 supports a steam super-heating pipe 16 and and this steamsuper-heating pipe 16 is connected to a parallel superheating pipe 17 bymeans of a transversely extending connecting pipe 18, the )ipe 18 beingconnected to the pipes 16 and 17 at their rear ends, or, in other words,at the end opposite to the ipe 15. The parallel super-l1cating pipe 1?is in turn connected to a secondary super-heating pipe 19 by means of adiagonally extending pipe 20. The pipe 19 carries a plurality ofupwardly extending supporting rods 21 and upon these supporting rods 21is mounted a flame distributing plate 22, the rods 21 passing throughthe apertures 23 formed in the plate 22. Flame distributing apertures 24are formed in the plate 22 and are adapted to distribute the flamethroughout the entire length of the plate so as to produce an evenheating surface. A secondary baille plate 25 is supported upon the pipes19 and 17 in the manner as illustrated in Fig. 3 so as to allow theflame from the burner to be distributed over the super-heating pipes 16and 1.7 to producean eliieicnt combustion.

The pipe 19 is provided with a downwardly extending discharge pipe 26which carries a discharge nozzle or cap 27 over which nozzle is placedthe burner pipe 28. This burner pipe 28 is provided with a plurality ofapertures 29 which are arranged in parallel rows for causing the blazeto be discharged in the path of the pipes 16, 17 and 19, as shown inFig. 8. The burner pipe 28 is secured over the cap 27 by means of theslot 30 fitting over the pin 31 and in this manner may be easilydetached from the cap so as to be cleaned it it be so desired. It shouldbe further understood that the pipe 15 is readily detached from the stubpipe 14, thereby also allowing access to be had to the interior of theboiler 5 for the purpose of removing sediment or other accumulationwhich may be settled in the boiler. The boiler 5 is provided at one endwith a pipe supporting bracket 31 adapted to engage the super-heatingpipe 16 at its far end so as to support the same and relieveconsiderable of the strain from the pipe 15. A plurality of spacedbrackets 32 are also mounted upon the tray 1 along the edge thereof andengage the pipe 19 to constitute an eflicient support to hold the burnerpipe 28 above the floor or base of the tray or pan 1 to allow a freecirculation of air under the Jan. I It should be understood that thepresent device may be placed in a desired position within the stove toaccomplish the desired purpose. An oil supply pipe 33 is connected tothe pipe 19 at its far end and this pipe carries a needle valve 34 forcontrolling the passage of oil therethrough, the oil passing into thepipe 19 through the aperture 35 formed in the outer end of the pipe. Asabove stated, a water supply tank 36 is employed in connection with thepresent invention, this supply tank 36 being suspended from a standard37 mounted upon the water supply tray 9. This water supply tray 9carries a sleeve 38 upon one side which constitutes a socket forreceiving the standard 37. This standard 37 is provided with anoverhanging end 39 in which is adjustably mounted a supporting hook 40,"said supporting hook carrying an adjusting nut ll for regulating theheight of the hook 40 upon the overhanging end 39. The tank 36 issuspended upon the hook by means of a bail 42 and this tank is alsoprovided with a supply opening 43 which opening is normally closed bymeans of the plug 44. The tank 36 is also provided with a valve casing45 at its lower end in which Works a valve 46 normally held in a closedposition by means of a spring 47. The bottom of the tank 36 is held inalinement with the tray 9 by means of guiding brackets 48 which guidingbrackets engage the sides or" the tank and prevent the lateral movementof the tank relative to the tray 9. If it is desired to allowconsiderable water to pass through the system, the supporting hook 40may be adjusted so as to allow the tank 36 to descend upon the tray 9 soas to hold the valve 46 widely open. If only a small quantity of wateris desired to flow through the system, the supporting hook 40 may be wso adjusted as to hold the valve 4-6 in a closer arrangement with thevalve seat and allow only a small amount of water to pass therethrough.

The cap 27 is provided with an aperture l9 which will allow the oil,before lighting the burner, to pass through'the pipe 19, through thepipe 26, and be discharged out through the aperture 49 into the bottomof the pan 1 whereupon the oil will saturate the asbestos plate 4L- andby applying a match thereto the oil. will become ignited and the heatwill generate steam within the boiler 5. The steam will then pass upthrough the pipe 15, through the pipes 16, 18 and 17,

through the pipe 20, through the pipe 19 mixing with the oil passingtherethrough, and vaporize the same by reason of the heat and therebyproduce carbon which takes up the oxygen of the water and separates theoxygen from the hydrogen and passes down into the tube 26, the cap 27,and thence coming out through the perforations 29 formed in the burnerpipe 28, producing an eflicient combustion. The flames will then strikethe balfie plate 25 and be distributed well over the pipes 16 and 17 andwill also be distributed against the plate 22 and in turnpassing throughthe apertures 24 formed therein.

The pan or tray 1 is adapted to fill the entire space in the stove,shutting out any chance for the air passing up by the sides of theflanges 2, thereby causing all of the air to pass through the aperturesor perforations 3 in the pan to produce an'eificient upward current ofair through the burner.

It will be seen by carefully considering Fig. 1 that the tank 36 islarger than the receiving pan 9 and the side edges of this tank 36overhang the sideedges of the receiving pan 9 so as to prevent the dustor dirt which might accumulate upon the outside of the tank 36from'dropping into the pan 9 and causing a sediment to be depos- V itedthereon.
